C1rcle: My Poser 4 never goes trolling through folders. It loads the list of textures when it opens and hunts in memory. It doesn't even care what's in the reference unless the texture isn't in its list in memory so it doesn't matter what the reference contains. It just looks at the texture name. So I really think your speed up of Poser must be due to something else. Try this. Make copies of a MAT file and change the references in it. One to the exact path/filename. One to an erroneous path but correct filename. One to a correct path but erroneous file name. Then test each. This would be under Poser 4. Because according to darlisa, Poser 5 won't find the texture in a different runtime if the path is not a valid one (it can be an incorrect one though) but it does under Poser 4. My results show that as long as the texture is somewhere in runtime:textures Poser finds it without problem or slowdown no matter whether the reference is correct or incorrect.
